THEODORE K. SAWYEBS, OF MONROE TOWNSHIP, MORGAN COUNTY, IND., ASSIGNOR OF ONE HALF OF HIS RIGHT TO SAMUEL O. HARPER, OF

SAME PLACE.

RUNNING-GEAR FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 225,876, dated March 23, 1880.

Application filed J annary 6, 1880.

To all whom it may concern:

Be itknown that I, THEODORE K. SAWYERs, of the township of Monroe county of Morgan, and State of Indiana, have invented certain new and useful Improvements in Circle-Track Wagons, of which the following is a specification, reference being had to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indi- 1o cate similar parts.

Figure l is a top or plan view of the running-gear of a wagon embodying my improvements in position as when moving directly forward. Fig. 2 is a similar view in position as 1 when moving on a curve or circle. Fig. 3 is a longitudinal vertical section looking toward the reach from the dotted line 00 w in Fig. 1.

In said drawings, the portions markedA A represent the wheels of the wagon B B, the

axles; C- O, the sand-boards; D D, the bolsters; E, the front hounds; F, the rear hounds; G, the pole or reach connecting the front and hind portions of the running-gear, to which it is attached by the king-bolts G G; H, a bar 2 5 or rod pivoted or hinged to the sand-board, axle, or some other rigidly attached portion of the front gearing; I, a shorter bar or rod, pivoted or hinged to the rear hounds or some other rigidly attached portion of the hind gear- 0 ing; J, a device pivoted or hinged to the reach G; K, abolt by which the parts H I J are connected together.

My invention consists in the application to the running-gear of a Wagon, the front and 3 5 rear portions of which are connected by a loosely-pivoted reach, of the three elements H I J, when arranged to operate to cause the rear wheels to follow the front ones in turnin g the wagon in the manner common to that class of vehicles known as circle-track wagons, of which my present invention is a good example.

The merits of my invention consist in its simplicity and cheapness, and in the fact that by its use the front and hind wheels must always occupy the same relative position in turning, and thus always track perfectly, no matter what the distance between them-a feature which most of the devices for the purpose do not possess.

The distance between the front and rear axles is diminished or increased by simply changing the various pins and bolts from one to another of the holes shown in the reach G and the bar H.

If it is desired to have the gearing of greater strength, the parts composing my device can be simply duplicated, in which case the duplicate of the rod H would cross it in the form of an X, and the duplicates of the rod I and the device J would preferably, though not necessarily, be attached to the front instead of the hind portion of the running-gear. Where but a single device is used, it may be attached to either end, as desired.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a circle-track wagon, the combination of the rods H and I and the device J, attached and operating substantially as set forth.

2. The combination of the front and rear portions of a wagon running-gear, the looselypivoted reach G connecting them, the bar H, hinged or pivoted to one portion, the bar I, hinged or pivoted to the other, the device J, hinged or pivoted to the reach, and the three parts H I J, connected together by the bolt K, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 2d day of January, A. D. 1880.

THEODORE K. SAWYERS.

In presence of- G. BRADFORD, WM. J. MILLNER.
